Summary

Multiple vulnerabilies in Apache Tomcat affect IBM UrbanCode Release.

Vulnerability Details

CVEID:

CVE-2016-0763

DESCRIPTION:

Apache Tomcat could allow a remote attacker to bypass security restrictions,
caused by an error in the ResourceLinkFactory.setGlobalContext() method. By
injecting malicious content, an attacker could exploit this vulnerability to
read and write arbitrary data.

CVSS Base Score: 6.5

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/110858

for the current score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)

CVEID:

CVE-2015-5345

DESCRIPTION:

Apache Tomcat could allow a remote attacker to obtain sensitive information,
caused by an error when accessing a protected directory. By redirecting to
the URL, an attacker could exploit this vulnerability to determine the
presence of a directory.

CVSS Base Score: 5.3

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/110857

for the current score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:

CVE-2015-5346

DESCRIPTION:

Apache Tomcat could allow a remote attacker to hijack a valid user's session,
caused by the failure to recycle the requestedSessionSSL field when recycling
the Request object to use for a new request. By persuading a victim to visit
a specially-crafted link and log into the application, a remote attacker
could exploit this vulnerability to hijack another user's account and
possibly launch further attacks on the system.

CVSS Base Score: 4.3

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/110854

for the current score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N)

CVEID:

CVE-2015-5351

DESCRIPTION:

Apache Tomcat is vulnerable to cross-site request forgery, caused by improper
validation of user-supplied input by the index page. By persuading an
authenticated user to visit a malicious Web site, a remote attacker could
send a malformed HTTP request to perform unauthorized actions. An attacker
could exploit this vulnerability to perform cross-site scripting attacks, Web
cache poisoning, and other malicious activities.

CVSS Base Score: 8.8

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/110859

for the current score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID:

CVE-2016-0706

DESCRIPTION:

Apache Tomcat could allow a remote attacker to bypass security restrictions,
caused by the loading of the StatusManagerServlet during the configuration of
a security manager. An attacker could exploit this vulnerability to obtain
deployed applications and other sensitive information.

CVSS Base Score: 5.3

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/110855

for the current score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:

CVE-2016-0714

DESCRIPTION:

Apache Tomcat could allow a remote attacker to bypass security restrictions,
caused by an error in multiple session persistence mechanisms. By placing a
malicious object into a session, an attacker could exploit this vulnerability
to bypass a security manager and possibly execute arbitrary code on the
system.

CVSS Base Score: 7.3

CVSS Temporal Score: See
